These bits are for test purposes and should not be changed from their default values of 00 0100b.

VPP12_ENB
RW
Controls 12-V VPP requests to the TPS power switch.
0 = 12-V VPP requests are filtered and passed as GND VPP requests (default).
1 = 12-V VPP requests are passed directly to the TPS power switch.
Controls 1.8-V VPP requests to the TPS power switch. 1.8-V requests are generated when either a
VPP request is made to an UltraMedia or CardBus card that requires 1.8-V VPP per the interrogation
process.
0 = 1.8-V VPP requests are passed to the switch as 12-V VPP requests (default).
1 = 1.8-V VPP requests are passed to the switch as 1.8-V VPP requests.
Reserved. These bits return 0s when read.
